For some reason, every time you used such an outrageously powerful energy, you found your mind being influenced. Your personality seemed to change as well, and you felt yourself gradually becoming numb and brutal.

This made you even more cautious, and for you, the fewer times you used this black and white light, the better!
Thinking this, you suddenly turned around and stared coldly at the man in the suit.
The man in the suit finally realized something was wrong, your strength had completely exceeded his expectations.
